Why Choose Engine Finders for Your Mercedes-Benz A-Class Engine?

Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Mercedes-Benz A-Class replacement engines. From M260 and M264 petrol units to OM654 diesel powerplants found across the W176/W177 generations, we address series-wide failure patterns like timing chain wear in early M260 engines and high-pressure fuel pump degradation in later M264 variants—ensuring you get the right engine matched to your chassis and drivetrain.

  • ✔ A-Class-Wide M260 Timing Chain Resolution

    We replace the tensioner (OEM A2600500315) and guide rails across all W176 A-Class models using Mercedes-Benz Technical Service Bulletin LI-19-03–compliant kits to prevent catastrophic chain skip failures common after 70k miles.

  • ✔ OM654 Diesel EGR Cooler Reliability

    All W177 A-Class OM654 engines share the same EGR cooler (OEM A6540940001), prone to internal cracking due to thermal cycling. We install upgraded coolers with reinforced brazing to eliminate coolant contamination risks.

  • ✔ M264 High-Pressure Fuel Pump Longevity

    The M264’s HPFP (OEM A2640700201) fails prematurely across A200–A250 variants due to inadequate lubrication. Our reconditioned engines include revised camshaft lobes and updated pump internals per MB Recall 24V-112 guidelines.

  • ✔ Series-Wide Turbocharger Compatibility

    Whether your A180 or A220 uses the M260 or M264, both rely on BorgWarner turbochargers (OEM A2600940003) with identical bearing failures. We rebuild with ceramic-coated shafts and improved oil seals for extended life.

  • ✔ Correct ECU Calibration for All Chassis

    W176 (2012–2018) and W177 (2018–present) A-Class models require distinct ECU mappings (part A2609000001 / A2649000002). We ensure your replacement engine includes the correct software version to avoid limp mode or misfire codes.

  • ✔ Shared Mounting System Precision

    All A-Class engines use identical hydraulic mounts (OEM A2602400101) across petrol and diesel variants. We verify mount compatibility to prevent vibration transfer and premature transmission wear post-installation.

  • ✔ Series-Covered Warranty Protection

    Every engine comes with a minimum 12-month warranty covering M260/M264/OM654-specific failure points—including timing systems, turbos, and fuel pumps—backed by suppliers certified in A-Class platform diagnostics.

  • ✔ Nationwide Access to A-Class Specialists

    Our network includes workshops trained on both W176 and W177 platforms, ensuring your A160 through A35 AMG receives engine replacements with correct ancillary alignment, wiring harness routing, and emissions compliance.

Mercedes-Benz A-Class Engines for Sale | Engine Finders

Engine Finders connects UK drivers with specialists for reliable, reconditioned Mercedes-Benz A-Class replacement engines. Whether tackling M270 timing chain wear in early W176 models or M260 direct-injection carbon buildup in W177 variants, we deliver OEM-spec solutions built for the full A-Class range.

Mercedes-Benz A-Class Replacement Engines

The A-Class spans two key generations: W176 (2012–2018) and W177 (2018–present). Both share core engine families—M270/M274 (W176) and M260/M264 (W177)—with common failure points. Early M270 petrol units suffer from timing chain tensioner wear, while M260 engines face high-pressure fuel pump and turbo wastegate issues across all trims. Mercedes-Benz Technical Bulletin LI-19-03 addressed oil consumption in M270 engines, a concern affecting 180–250 variants alike. Despite updates, shared architecture means reliability challenges persist series-wide, not just in individual models.

Mercedes-Benz A-Class Models & Engines Codes

Engine families are consistent across A-Class generations, with compatibility spanning multiple trims:

  • M270 DE16 LA: 1.6L petrol (W176, 2012–2018) – Timing chain tensioner (A2700500607) wear affects all 180/200 variants
  • M274 DE20 LA: 2.0L petrol (W176, 2012–2018) – Oil consumption issues per MB LI-19-03 bulletin
  • M260 E16 DEH: 1.3L turbo petrol (W177, 2018–present) – Turbo actuator failures across 160/180/200 models
  • M264 E20 DEH LA: 2.0L turbo petrol (W177, 2018–present) – High-pressure fuel pump (A2740700607) weakness in all outputs
  • OM654 DE20 LA: 2.0L diesel (W177, 2018–present) – EGR cooler cracking due to shared casting design

All engines fit direct OEM mounts across W176/W177 chassis, enabling cross-generation compatibility with matching ECUs.

Buy Used and Second-Hand Mercedes-Benz A-Class Engines

For the A-Class, engine type choice depends on generation-specific risks:

  • Rebuilt: Essential for W176 M270 units—includes updated tensioner (A2700500607)
  • Remanufactured: Recommended for W177 M260/M264—features upgraded HPFP and turbo seals
  • Used: Only viable for low-mileage OM654 diesels with verified service history

All options undergo compression and leak-down testing to ensure MoT compliance across the A-Class range.
